A Bit of Exercise, But a Lot of Benefit

There's been a plethora of research lately documenting the healthbenefits of any sort of exercise, no matter how modest. The mostrecent documents a twelve-week study of 106 sedentary middle-agedfolks who were assigned to one of three regimens: walking thirtyminutes three days a week; walking thirty minutes five days a week;or doing nothing at all.

The walkers were even allowed to break their thirty-minute stints upinto three bouts of ten minutes long. Really, you can't get mucheasier than that.

For the non-walkers, on the other hand, nothing changed. Even asmall reduction in blood pressure and waist circumference can lowerrisk of cardiovascular disease, and who couldn't use a bit morefunctional capacity? It's a pretty good payoff for a mere half-hourthree times a week.
